Which statement accurately describes how WDXRF and EDXRF differ in detector technology and typical use?

• A. WDXRF uses a crystal to separate wavelengths for high-resolution spectra; EDXRF uses a crystal for energy-dispersive spectra.
• B. WDXRF uses a crystal to separate wavelengths for high-resolution spectra; EDXRF uses a silicon-based detector for energy-dispersive spectra.
• C. WDXRF relies on a simple light detector, while EDXRF uses multiple detectors.
• D. EDXRF cannot analyze solids.

Answer: (B)
